Referring more particularlyto the drawings, wherein like charactersindicate like and corresponding parts throughout the several views, Aindicates the structure or partof the apparatus which is particularlydesigned for use in the dismembering and assembling of locomotives, Bindicates the structures particularly designed to facilitate thedismembering and assembling of rolling stock, such as passenger cars,freight cars, and the like, while the structure which is employed forcarrying the parts of a locomotive or other rolling stock to the shopsis generically indicated by the letter C.

ln installing the apparatus, a pit' 10 is dug longitudinally in whichordinary T- rails 11 and 12 are mounted to form a track over which thecar 13 travels. lThis car 13 includes a platform 14 which has suspendedtherebeneath axles 15 carrying flange wheels 1G adapted to ride over theT-rails 11 and 12 of the track structure. The platform 14 of the car 13has rails 17 thereon the gage of which is equal to the gage of anordinary rail track, with which the said rails are adapted to aline topermit the running of an engine or locomotive thereon, when it isdesired to dismember the same.

A super-structure is built over the pit y 10 near one end of the sameand it supports suitable I beams 21 forming tracks for block and tacklehoist structure 22, the chains of which are adapted to engage about theboiler of a locomotive, the tank of a tank car or the like for liftingthe boiler or tank from the running gear structure of a locomotive ortank car. ln the drawings a locomotive is shown positioned upon the car13, and ready to be dismembered. Suitable saddles 23 may be provided forengagement beneath the boiler indicated at E of a locomotive D tosupport the boiler in position for remounting upon the truck structureof a locomotive.

T he upper surface of the platform 14 of the car 13 normally lies belowthe ground surface in which the pit 10 is dug and when it is desired torun a locomotive upon the car, the latter is moved until it alines withany one of a series of transversely extending tracks 26 and the hoistsor hydraulic jack structures 27 are operated by means of the pump 28, toelevate the car structure 13 to move the upper surface thereof flushwith the ground surface upon each side of the pit 10. T he pumps 28 areoperated from shafts 29 by means of disks 30 and rods 31 which areeccentrically connected tothe said disks 3() as clearly shown in Figs. 2and 3 of the drawings.

The shafts 29 at one side of the pit 10 is connected by means of beveledgears 32 to a shaft 33 which is adapted for operative connection to aclutch structure 34 with a shaft 35 which is in turn connected by meansof miter gears 36 with a shaft 3T which extends longitudinally along theside of the pit 10. The shaft 3T is operatively connected, by means of abelt and pulley transmission structure 38 with a shaft'39 which is inturn connected to a motor 40 or other analogous prime mover as clearlyshown in Fig. 3 of the drawings. The shaft 29 at the opposite side ofthe pit 1() from that just described is connected by means of a beveledgear 41 to a shaft 42 which is connected through the clutch structure 43with a shaft 44. The shaft 44 is connected by means of miter or beveledgears 45 with a second shaft 46 which extends longitudinally along thepit 10. This shaft 4G is connected by means of a belt and pulleytransmitting structure 47 with the kshaft 39. 1While in the drawings atwo shaft and cone clutch structure is illustrated for connecting theshafts 39 and 27 and 29 and 46 respectively, it is to be understood thatany approved type of clutch mechanism used in connection with a singleshaft may be employed in lieu of the two shaft and cone clutch structurewithout departing from the spirit of this invention. The clutches 34 and43 are operated by means of hand levers 48, which carry the usual typeof dog mechanism 49 adapted for co-action with quadrants 50 for holdingthe hand levers in adjusted positions and these levers preferablyproject upwardly through openings formed in the platform 51 positionedat each side of the pit 10, while the various shafts are preferablypositioned in pits 52 placed at each side of the pit 1() and separatedfrom the pit 10 by partitions 53.

The motor or prime mover 40, together with the shafts 39 and the pulleyscarried 1y said shafts for connection with the shafts 3T an d 4Grespectively are preferably placed in a pit 54 located beneath the pit10 and separated therefrom by a removable cover 55, countersunk so thatits upper edge will lie flush with the bottom of the pit 10.

Suitable controls 56 for the valves of the hydraulic j ack or pumpstructures 27 and 28 are provided which also project upwardly throughthe platforms 51.

Cushioning .structures 57 are provided for cushioning the downwardmovement of the car structure 13 or for holding the car structureagainst accidental movement under its own weight should the hydraulicpump or jack structure break or otherwise fail to operate.

These cushioning structures include cylinders 58 in which are mountedpistons 59, the piston rods 60 of which engage against the undersurfaces of girders 61 carried by the car structures 13 and to whichgirders the piston rods 60 are connected by means of hooks or analogouscoupling means (S2 so that when the car structure 13 is elevated by theoperation of the jack structures 28, the piston 59 will be movedupwardly in the cylinders 58. 'A relatively large pipe 63 hascommunication with the cylinder 58 at its upper and lower ends and acheck valve G4 is positioned in each of these pipes 63 near their lowerends, so as to permit fluid to pass from the cylinder 58 above thepiston 59 through the pipe G3 past the check valve structure G4 and intothe cylinder below the piston 59, but prevents fluid from passing out ofthe cylinder 58 below the pistons to the pipe into the cylinder abovethe piston. The passage of fiuid from within the cylinder below thepiston 59, into the cylinder above the piston is had through arelatively small pipe in which a valve (36 is placed, near its lowerend, and by operation of this valve through the medium of the valveoperating structure 6T, the flowing of the fluid from the cylinder belowtne piston into the cylinder above the piston may be controlled. Bymaking the pipe 65 much smaller than the pipe 63, the upward flow offluid out of the cylinder will be materially less than the downward flowof fluid through the pipe 63, providing suliicient retarding to allowthe car structure 1li to slowly move downwardly into the pit to preventshock or jars being administered to the car structure and its loadduring its lowering movement.

After the car 13 and its load has been lowered into the pit so that thewheels 1S ride upon the rails 11 and 12 the said car is movedlongitudinally in the pit by cables and 71 one of which is connected tothe platform 14 of the car 13 at each side thereof. The cable 70 extendssubstantially the full length of the pit 10 intermediate the ails 11 and12 and passing about a suitable guide sheave 72 at the end of the pit tr tending transversely to the pit from this sheave and about a secondguide sheave T3 from which it extends parallel to the pit until itreaches the guide pulley i which directs it again in a direction'transversely to the length of the pit whereit is connected to a drum.75 loosely mounted upon the shaft 37. ,1i clutch section To is carriedby one end of the drum 75 and is adapted for co-action with a clutchsection 77 feathered upon the shaft 37 for rotating` the drum 75 by therotation of the shaft to wind the cable 70 thereon to draw the car andits lo? d longitudinally in the pit 10. During the winding of the cable70 upon the drum 75, the cable 71 will unwind from its carrying` drum78, which drum is rotatively mounted upon the shaft L16 and has a clutchsection 79 carried thereby adapted for coaction with a clutch. section80 feathered upon the shaft lo to rotate the drum T8 by the rotation ofthe shaft i6 to wind the cable T1 thereon to move the car 13 indirection reversely to that which it is moved in when the cable '7G iswound upon the drum 75.

The clutch sections 77 and 80 are shifted by hand levers 81. The cable71 passes over suitable guide pulleys 82 between its connection with car13 as shown at 88 and the drum 78.

A plurality of tracks S5 extend across the platform 51 between the pits10 and 86. Rails 8'? and 88 are positioned in the pit 86, to form atrack therein upon which is mounted a car 89, having a track structure90 upon its upper surface adapted for alinement with any one of thetracks to permit the movement of a locomotive, car or a part thereononto the car 89, for moving over the tracks formed by the rails 8i' and88, to carry the said part of the locomotive or rolling stock to a shopor house as shown at 91 and 92 in Fig. 1 of the drawings. lfor instance,the shop 91 is provided with machinery for the repairing of the engineand truck of a locomotive, when the excessive repairs are neededthereon, and in such cases, a locomotive is run from the car structure13 over one of the tracks 85 upon the car structure S9 which latter carstructure is moved along the rails S7 and 88 upon the tracks upon thecar alined with the tracks 93 which lead into the shop 91 at which pointthe engine and truck structures of the locomotive are run off the car S9into the shop 91. ln cases where excessive repairs are needed upon theboiler structure of the locomotive, the same is placed upon a car 911,which car is run upon the track upon the car S9 after which the car 89is moved along the rails S7 and S8 until it alines with the tracksleading into the shop 92, at which point the car 9e carrying the boilerstructure E is run off the car 89 into the shop 92. it suitable truckstructure 95 of the t lestle type is provided, having rollers 96 carriedby the lower ends of its legs 97 which trestle or truck structure isadapted to support the boiler E when the latter is moved into J`V'ieshop 92 to permit movement of the shop for repairs, .in places where notracks are provided.

ln cases where only slight repairs are needed upon the boiler structurelll, the car 13, after the boiler tructure and engine structure of thelocomotive have been dismembered is lowered upon the rails 11 and 12 andmoved longitudinally in the pit 1 9, moving it away from beneath theboiler, structure E where the necessary slight repairs may bei` made tothe engine or truck structure, and the boiler is lowered so that it willbe accessible to workmen from the bottom of the pit 10 and rests upon asuitable trestle structure 9S which is hingedly connected as shown at 99to the bottom of the pit 10. Angled. braces 100, which includeturnbuckles 101 therein are provided for connection with the trestle 98to rigidly support it in an upright position and they are adapted fordetachable pivotal conneotion to suitable coupling` structure 102 whichare carried by the floor or bottom of the pit 10. 1f it is so desired,cables 103 and 104l may be connected to the car 89 and have any suitabletype of operating means connected thereto for pulling the car S9 overthe rails 87 and 88. However it is to be imderstood that this car 89 maybe propelled manually over the rails or by any suitable structurewithout departing from the spirit of this invention.
